Answer:

Option c (2.27) is the right option.

Step-by-step explanation:

As per the question, the values are:

<u>Credit hours                                       Grade                                 fiXi</u>

       (fi)                                                   (Xi)                              

<u>         4                                                  B = 3                                   12</u>

<u>         3                                                  C = 2                                   6</u>

<u>         1                                                   A = 4                                   4</u>

<u>         3                                                  D = 1                                    3       </u>

Now,

\Sigma fi= 25

\Sigma fiXi = 25

hence,

The average will be:

= \frac{\Sigma fiXi}{\Sigma fi}

On putting the values, we get

= \frac{25}{11}

= 2.27

The vertices of ABC are A(-2, 2), (6,2), and (0,8). Its area is _ square units.​
kiruha [24]

Answer:

T = 24 so it would be 24x24=576 square units

Step-by-step explanation:

How did we calculate this triangle?

The calculation of the triangle progress in two phases. The first phase is such that we try to calculate all three sides of the triangle from the input parameters. The first phase is different for the different triangles query entered. The second phase is the calculation of other characteristics of the triangle, such as angles, area, perimeter, heights, the center of gravity, circle radii, etc. Some input data also results in two to three correct triangle solutions (e.g., if the specified triangle area and two sides - typically resulting in both acute and obtuse) triangle).

What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tent
Verdich [7]

Answer:

766.3 square inches

Step-by-step explanation:

The volume of pyramid is given by  

volume = 1/3(area of base) * height of pyramid

Given shape of base is square and

Perimeter of that square is 44inches

We know that perimeter for square is given by 4* length of side

Thus,

44 inches = 4* length of side

 Length of side = 44/4 = 11 inches  

_____________________________________________

Area of square is given by side*side.

Thus, area of square base of pyramid is = 11*11 inches square = 121 inches square

Now that we have area of base and height of pyramid .

Substituting these value in formula for volume of pyramid we have

volume = 1/3(area of base) * height of pyramid

 volume = 1/3*(121) * 19 = 2,299

 volume = 766.33

Volume of square pyramid rounded to nearest tenth is 766.3 square inches

Daniel is reading a 200-page book. He
Minchanka [31]

Set up a ratio to find the number of pages read in 80 minutes:

40 pages/ 50 minutes = x pages/ 80 minutes

Cross multiply:

50x = 3200

Divide both sides by 50:

X = 3200/50

X = 64

He will read 64 pages in 80 minutes.

200 -64 = 136

There will be 136 pages left.
